In response to initialization, embodiments perform a shredding step comprising shredding the explain text of the request; and populating a plurality of metadata tables comprising a superset table required for internal processing. Next, embodiments define or redefine a machine learning algorithm comprising a plurality of rulesets by calling a plurality of macros to act on the request; access a historic log comprising identified performance tuning parameters configured for tuning queries; and use the identified performance tuning parameters and the machine learning algorithm, optimize the query, thereby resulting in an optimized query.

BACKGROUND

Manual interactions between users and third parties that traditionally involve manual or face-to-face conveyance of data and information are inefficient, slow, and often insecure thereby reducing productivity and security associated with all parties involved. As such, there exists a need for a system to improve the efficiency, speed, and data security when performing interactions.

BRIEF SUMMARY

The following presents a simplified summary of the present disclosure in order to provide a basic understanding of some aspects of the invention. This summary is not an extensive overview of the invention. It is not intended to identify key or critical elements of the invention or to delineate the scope of the invention.

DETAILED DESCRIPTION OF THE INVENTION

Embodiments of the present invention now may be described more fully hereinafter with reference to the accompanying drawings, in which some, but not all, embodiments of the invention are shown. Indeed, the invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure may satisfy applicable legal requirements. Like numbers refer to like elements throughout.

A “system environment”, as used herein, may refer to any information technology platform of an enterprise (e.g., a national or multi-national corporation) and may include a multitude of servers, machines, mainframes, personal computers, network devices, front and back end systems, database system and/or the like.

Teradata® is a data management and analytics company and platform that provides integrated data warehousing, big data architectures and software, cloud services for data analytics, data lake products, advanced analytics and HADOOP and open source solutions. As used herein, reference to Teradata refers to its integrated data warehousing, architecture, cloud services and analytics. As used herein, an example of a data management structure is one or more of the Teradata solutions.

Teradata performance tuning typically poses a challenge considering the high volume of the data and the deep architectural knowledge required. Because many Teradata users (i.e., consumers) come from different relational database management system (RDBMS) backgrounds, such programmers may find it difficult to design their queries, thereby resulting in either SPOOL out or over-processing issues. Sometimes, the processes may be killed by the database administrator if the database consumes more resources than a predetermined threshold. Thus, entity remediation teams may receive and remediate numerous request for incident investigation related to performance issues in a given time period. For each such incident investigation, detailed business analysis may be required in order to identify problematic areas and multiple full-time employees may work to manage all critical failures that may affect business.

While entities may determine and implement best business practices, database query tuning is a niche skill as it requires detailed understandings of the system configurations and in some cases requires optimizing a dynamic plan and potentially solutions to reduce the processing resource consumption. Thus, based on tested results, a standard manual analysis helps to resolve only approximately 40% of the incident issues. The remaining issues requires substantial trial and error as similar techniques may not apply for all environments.

Thus, embodiments of the invention leverage a combination of a Teradata RDBMS, shell scripting, HADOOP, SPARK ML and PYTHON, as well as a .Net web and reporting tools for the presentation layer of the system. The innovative tool analyzes each and every step of a query plan against a current configuration of the system, log history, user profile, relational set, deep dive on the impacted data and compares the allocated versus the required spool. The tool analyzes a host of performance remediation parameters including spool space, non-compliant steps as per the threshold defined for the system, stale statistics, User-Defined Function (UDF) usage, join strategy, processing and input/output skew, unnecessary input/output and system impact. The tool is easily deployable to all Teradata users and no deep architecture knowledge is required. A user can run the tool as many times as necessary and the problematic queries will be remediated by optimizing the query by re-writing it.

FIG. 1 provides a block diagram illustrating an environment 100 wherein a system for analyzing, optimizing and remediating a proposed data query prior to query implementation may be implemented. Likewise, the environment may enable a real-time artificial intelligence engine for leveraging historical data as discussed below. As depicted in FIG. 1, the operating environment 100 may include a user system or user device 200 that may include one or more user systems (i.e., user devices), computer, servers, network and/or the like. As shown, the user system may communicate with other devices and systems or over the network 150 or embodiments of the invention may establish communication linkages directly or indirectly between and/or among two or more of the devices that are part of the environment 100.

In various embodiments, the environment may also include a database system 400 interacting with the user system 200 of a user 105, one or more remote devices 401, one or more entity devices 402, and/or one or more database system(s) 400 using a network 150 that includes an internet 151 and wireless telephone network 152. In some embodiments, the database system 400 may be maintained by a financial institution. In some embodiments, the database system 400 may be owned and maintained by the financial institution. The user 105 and other plurality of users may be system resources (hardware and/or software), customers of the entity, or third party entities.

The environment 100 also may include a plurality of computing devices of the user 105. The computing devices may include any machine, apparatus, system or the like that may be connected to and communicate with other devices over a network 150. The user system 200 may include a personal computer such as a desktop computer, laptop computer, tablet or any type of personal computing device that may be connected to a network by landline or wireless access such as wireless local area network (WLAN) such as Wi-Fi based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards, Bluetooth short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485 GHz or other wireless access technology.

Referring now to FIG. 2, the user system 200 may be any computing device utilized by the user 105. In embodiments of the present invention, the user system may be any device of the user connected to the database system(s) via a direct wired (e.g., USB port), indirect wired/wireless (e.g., over the network) or direct wireless technology (e.g., Bluetooth). The user system may be any system, server, computing resource consumer, wearable device, laptop, mobile device, smart phone device, PDA, tablet, or any other mobile device. In one embodiment of the invention, there may be multiple user systems.

Some embodiments of the user system 200 include a processor 210 communicably coupled to such devices as a memory 220, user output devices 236, user input devices 240, and a network interface 260. The user system 200 further includes a power source 215, such as a battery, for powering various circuits and other devices that are used to operate the user system 200. Embodiments of the user system 200 may also include a clock or other timer 250 configured to determine and, in some cases, communicate actual or relative time to the processor 210 or one or more other devices. The processor 210, and other processing devices described herein, generally include circuitry for implementing communication and/or logic functions of the associated device. For example, the processor 210 may include a digital signal processor device, a microprocessor device, and various analog to digital converters, digital to analog converters, and/or other support circuits. Control and signal processing functions of the user system 200 are allocated between these devices according to their respective capabilities. The processor 210 thus may also include the functionality to encode and interleave messages and data prior to modulation and transmission. The processor 210 can additionally include an internal data modem. Further, the processor 210 may include functionality to operate one or more software programs, which may be stored in the memory 220. For example, the processor 210 may be capable of operating a connectivity program, such as a web browser application 223. The web browser application 223 may then allow the user system 200 to transmit and receive web content, such as, for example, location-based content and/or other web page content, according to a Wireless Application Protocol (WAP), Hypertext Transfer Protocol (HTTP), and/or the like. The memory device 220 may include other applications such as entity application 221, a user application 224, database application 225, authorization application 222, and/or the like. In some embodiments, the database application 225 may be a part of the entity application 221. In some embodiments, entity application 221 may be a mobile banking application. The database application 225 interacts with the database system(s) 400 to perform one or more functions. In some embodiments, the authorization application 222 allows the user system 200 to interact with entity systems and database system(s) 400.

The processor 210 is configured to use the network interface 260 to communicate with one or more other devices on the network 150. In this regard, the network interface 260 includes an antenna 276 operatively coupled to a transmitter 274 and a receiver 272 (together a “transceiver”).

By way of illustration, the user system 200 may be configured to operate in accordance with any of a number of first, second, third, and/or fourth-generation communication protocols and/or the like. For example, the user system 200 may be configured to operate in accordance with second-generation (2G) wireless communication protocols IS-136 (time division multiple access (TDMA)), GSM (global system for mobile communication), and/or IS-95 (code division multiple access (CDMA)), or with third-generation (3G) wireless communication protocols, such as Consolidated Mobile Telecommunications System (UMTS), CDMA2000, wideband CDMA (WCDMA) and/or time division-synchronous CDMA (TD-SCDMA), with fourth-generation (4G) wireless communication protocols, with LTE protocols, with 3GPP protocols and/or the like. The user system 200 may also be configured to operate in accordance with non-cellular communication mechanisms, such as via a wireless local area network (WLAN) or other communication/data networks.

The network interface 260 may also include a near field communication (NFC) interface 270. As used herein, the phrase “NFC interface” generally refers to hardware and/or software that is configured to contactlessly and/or wirelessly send and/or receive information over relatively short ranges (e.g., within four inches, within three feet, within fifteen feet, and the like). The NFC interface 270 may include a smart card, key card, proximity card, Bluetooth® device, radio frequency identification (RFID) tag and/or reader, transmitter, receiver, and/or the like. In some embodiments, the NFC interface 270 communicates information via radio, infrared (IR), and/or optical transmissions. In some embodiments, the NFC interface 270 is configured to operate as an NFC transmitter and/or as an NFC receiver (e.g., an NFC reader). Also, it will be understood that the NFC interface 270 may be embedded, built, carried, and/or otherwise supported in and/or on the user system 200. In some embodiments, the NFC interface 270 is not supported in and/or on the user system 200, but the NFC interface 270 is otherwise operatively connected to the user system 200 (e.g., where the NFC interface 270 is a peripheral device plugged into the user system 200). Other apparatuses having NFC interfaces mentioned herein may be configured similarly. In some embodiments, the NFC interface 270 of the user system 200 is configured to contactlessly and/or wirelessly communicate information to and/or from a corresponding NFC interface of another apparatus (e.g., a point of sale (POS) device, an automated teller machine (ATM) or another mobile or computing device). In one embodiment of the present invention, the NFC interface of the user system 200 wirelessly communicates information (virtual card information such as virtual card number, CVV code, expiration date) stored in the user application 224 to perform a transaction.

As described above, the user system 200 has a user interface that may be made up of user output devices 236 and/or user input devices 240. The user output devices 236 include a display 230 (e.g., a liquid crystal display or the like) and a speaker 232 or other audio device, which are operatively coupled to the processor 210. The user input devices 240, which allow the user system 200 to transmit data, may include any of a number of devices allowing the user system 200 to transmit data, such as a keypad, keyboard, touch-screen, touchpad, microphone, mouse, joystick, other pointer device, button, soft key, and/or other input device(s). The user interface may also include a camera 280, such as a digital camera.

The user system 200 may also include a positioning system device 275 that is configured to be used by a positioning system to determine a location of the user system 200. For example, the positioning system device 275 may include a GPS transceiver. In some embodiments, the positioning system device 275 is at least partially made up of the antenna 276, transmitter 274, and receiver 272 described above. For example, in one embodiment, triangulation of cellular signals may be used to identify the approximate location of the user system 200. In other embodiments, the positioning system device 275 includes a proximity sensor or transmitter, such as an RFID tag, that can sense or be sensed by devices known to be located proximate a location to determine that the user system 200 is located proximate these known devices.

The memory 220 is operatively coupled to the processor 210. As used herein, “memory” or “memory device” includes any computer readable medium (as defined herein below) configured to store data, code, or other information. The memory 220 may include volatile memory, such as volatile Random Access Memory (RAM) including a cache area for the temporary storage of data. The memory 220 may also include non-volatile memory, which can be embedded and/or may be removable. The non-volatile memory can additionally or alternatively include an electrically erasable programmable read-only memory (EEPROM), flash memory or the like. The memory 220 can store any of a number of applications which include computer-executable instructions/code executed by the processor 210 to implement the functions of the user system 200 and/or one or more of the process/method steps described herein. For example, in one embodiment, a memory device may include any computer memory that provides an actual or virtual space to temporarily or permanently store data and/or commands provided to a processing device when it carries out its functions described herein. In some embodiments, data, profiles, or the like may be stored in a non-volatile memory distinct from instructions for executing one or more process steps discussed herein that may be stored in a volatile memory such as a memory directly connected or directly in communication with a processing device executing the instructions. In this regard, some or all the process steps carried out by the processing device may be executed in near-real-time, thereby increasing the efficiency by which the processing device may execute the instructions as compared to a situation where one or more of the instructions are stored and executed from a non-volatile memory, which may require greater access time than a directly connected volatile memory source. In some embodiments, one or more of the instructions are stored in a non-volatile memory and are accessed and temporarily stored (i.e., buffered) in a volatile memory directly connected with the processing device where they are executed by the processing device. Thus, in various embodiments discussed herein, the memory or memory device of a system or device may refer to one or more non-volatile memory devices and/or one or more volatile memory devices

These applications also typically provide a graphical user interface (GUI) on the display 230 that allows the user 105 to communicate with the user system 200, and/or other devices or systems. The memory 220 can also store any of a number of pieces of information, and data, used by the user system 200 and the applications and devices that make up the user system 200 or are in communication with the user system 200 to implement the functions of the user system 200 and/or the other systems described herein. For example, the memory 220 may include such data as user authentication information.

For example, the device may identify an input from a user via any of the user input devices and may alert the system.

The network communication interface 331 may also include a near field communication (NFC) interface. As used herein, the phrase “NFC interface” generally refers to hardware and/or software that is configured to contactlessly and/or wirelessly send and/or receive information over relatively short ranges (e.g., within four inches, within three feet, within fifteen feet, and the like). The NFC interface may include a smart card, key card, proximity card, Bluetooth® device, radio frequency identification (RFID) tag and/or reader, transmitter, receiver, and/or the like. In some embodiments, the NFC interface communicates information via radio, infrared (IR), and/or optical transmissions. In some embodiments, the NFC interface is configured to operate as an NFC transmitter and/or as an NFC receiver (e.g., an NFC reader). Also, it will be understood that the NFC interface may be embedded, built, carried, and/or otherwise supported in and/or on the user system 200. In some embodiments, the NFC interface is not supported in and/or on the user system 200, but the NFC interface is otherwise operatively connected to the user system 200. For example, user system 200 may be internally connected to the electronic and communication system of the entity system and may utilize the NFC interface of the entity system. In some embodiments, the NFC interface of the user system 200 is configured to contactlessly and/or wirelessly communicate information to and/or from a corresponding NFC interface of another apparatus (e.g., a point of sale (POS) device, an automated teller machine (ATM) or another mobile, remote device, vendor entity devices, or computing device).

The memory device 333 may include one or more applications or information accessed or received by the device 330. The memory device, as shown, comprises one or more applications including application 334, application 335, and/or the like.

FIG. 5 presents a process flow 500 for optimizing queries. The first step, as represented by block 510, is to receive a request (such as a query) from a user. The next step, as represented by block 520, is to perform an initialization of the process. This initialization step, which may also be referred to as stage one of the process, may include connecting to a data management structure (such as one or more Teradata products). The next stage of the process is the shredding stage, as represented by block 530. This step includes performing a shredding step that may include shredding the explain text of the request. The explain text may be part of the query that is formatted in XML. This phase also includes populating metadata tables, resulting in a superset table.

Next, as represented by block 540, the process includes defining (or redefining if already defined) a machine learning algorithm having a plurality of rulesets by calling a plurality of macros to act on the request (i.e., query). Then, as represented by block 550, the process includes accessing a historical log with identified performance tuning parameters configured for tuning queries. Next, as represented by block 560, the process uses the tuning parameters and the algorithm to optimize the query, resulting in an optimized query. Next, as represented by block 570, the process send the optimized query to the user and/or automatically implements the optimized query, receive results and send results to user. Then, as represented by block 580, the process stores a copy of the query, the optimized query, the tuning parameters and the algorithm in the historical log for user in optimization of future queries. Finally, as represented by block 590, is in response to determining similarity of a new query to the original query, to use the stored query, optimized query, tuning parameters and algorithm to optimize the second query.

Referring now to FIG. 6, a flowchart illustrates a high level process for analyzing, optimizing, and remediating a proposed data query prior to query implementation, in accordance with an embodiment of the present invention. As shown, the first step of the overall process is receiving an SQL request from a host environment (and/or from a user). This stage is also referred to as initialization. Initialization is broken down into additional detail as shown in FIG. 7, as discussed further below.

As shown in FIG. 7, the initialization process involves a caller SQL input into Teradata. A WSH script is run that connects to Teradata to run the BTEQ export. The explain text of the SQL in XML format is exported and then the process disconnects from Teradata. This is call stage one (1).

Next, a WSH script connecting to a data management structure such as Teradata to run the BTEQ import. The explain plan of the SQL is imported in XML format and stored in character-large object format. Once this is done, the process moves on to overall process stage two as discussed below.

The next overall process stage is the XML shredding process as illustrated in further detail in FIG. 8 below. In this stage, the explain plan is shredded and the system populates the respective metadata tables required for internal processing. In the shredding process, the system shreds the captured explain plan in XML format, thereby resulting in resolved SQL, an analyzed queryplan, referenced components, join predicates, index predicates, filter predicates, and spool predicates.

The next stage of the overall process, as illustrated in more detail in FIG. 9 below is to call a number of macros, which affect spool space verification, non-compliant steps, stale stats identification, object skewness, null analysis (retrieval of join columns), User-Defined Function (UDF) usage (identification of UDF), distinct usage (identification of distinct usage, which is non-compliant), missing index/and join conditions (missing index or column join conditions).

As shown below in FIG. 10, the next stage of the overall process is the machine learning framework. As noted, the SQL query is input into the machine learning framework and a historic log (HDFS/HBASE) is accessed. The machine learning framework applies an SML shredding and provides the identified performance tuning parameters as input to the machine learning classification algorithm. Then, based on the output of the classification algorithm, the machine learning framework makes necessary changes to the query for optimized performance. The optimized query generated by the system is then sent to the user.

In conclusion, generally forecasting Teradata system resources and performance predicates do not consider the current Teradata environment, dynamic calculations using Machine/Deep learning algorithms and the business criticality. The present invention provides solutions for these problems by providing a system that, based on the detailed analysis and the data collected (and stored in the historical log), the automatic assistance framework predicates the flaws and assists the tuning recommendations for each category level using the Machine and Deep learning algorithms. The system then applies a query re-write pattern or collects the required missing or stale statistics.

In other embodiments of the present invention, however, the computer-readable medium may be transitory, such as, for example, a propagation signal including computer-executable program code portions embodied therein.

One or more computer-executable program code portions for carrying out operations of the present invention may include object-oriented, scripted, and/or unscripted programming languages, such as, for example, Java, Perl, Smalltalk, C++, SAS, SQL, Python, Objective C, JavaScript, and/or the like. In some embodiments, the one or more computer-executable program code portions for carrying out operations of embodiments of the present invention are written in conventional procedural programming languages, such as the “C” programming languages and/or similar programming languages. The computer program code may alternatively or additionally be written in one or more multi-paradigm programming languages, such as, for example, F #.

Some embodiments of the present invention are described herein with reference to flowchart illustrations and/or block diagrams of apparatus and/or methods. It will be understood that each block included in the flowchart illustrations and/or block diagrams, and/or combinations of blocks included in the flowchart illustrations and/or block diagrams, may be implemented by one or more computer-executable program code portions. These one or more computer-executable program code portions may be provided to a processor of a general purpose computer, special purpose computer, and/or some other programmable data processing apparatus in order to produce a particular machine, such that the one or more computer-executable program code portions, which execute via the processor of the computer and/or other programmable data processing apparatus, create mechanisms for implementing the steps and/or functions represented by the flowchart(s) and/or block diagram block(s).

The one or more computer-executable program code portions may be stored in a transitory and/or non-transitory computer-readable medium (e.g. a memory) that can direct, instruct, and/or cause a computer and/or other programmable data processing apparatus to function in a particular manner, such that the computer-executable program code portions stored in the computer-readable medium produce an article of manufacture including instruction mechanisms which implement the steps and/or functions specified in the flowchart(s) and/or block diagram block(s).

The one or more computer-executable program code portions may also be loaded onto a computer and/or other programmable data processing apparatus to cause a series of operational steps to be performed on the computer and/or other programmable apparatus. In some embodiments, this produces a computer-implemented process such that the one or more computer-executable program code portions which execute on the computer and/or other programmable apparatus provide operational steps to implement the steps specified in the flowchart(s) and/or the functions specified in the block diagram block(s). Alternatively, computer-implemented steps may be combined with, and/or replaced with, operator- and/or human-implemented steps in order to carry out an embodiment of the present invention.
